Answer:
q = 6/13, p = 35/13
Step-by-step explanation:
3p + 2q = 9
2p - 3q = 4
_________ (subtract the two equation from each other.)
p + 5q = 5
p = 5 - 5q
2(5 - 5q) - 3q = 4 (substitute value of p into equation)
10 - 10q - 3q = 4
10 - 13q = 4
-13q = -6
<u>q = 6/13</u>
3p + 2(6/13) = 9 (substitute value of q into equation)
3p + 12/13 = 9
3p = 105/13
<u>p = 35/13</u>

Answer: 84%
Step-by-step explanation:
112 grocery shoppers bought a candy bar and 588 grocery shoppers did not.
Number of grocery shoppers that bought candy bar = 112
Number of grocery shoppers that did not buy candy bar= 588
Total number of grocery shoppers= 112+588 = 700
Percentage of shoppers did not buy a candy bar= 588/700 × 100
= 0.84 × 100
= 84%
The answer to your question is 31.25 or 31 1/4
